Airworthiness Directives; Beech Aircraft Corporation Model 58P and 58PA Airplanes

Résumé

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Beech Aircraft Corporation (Beech) Model 58P and 58PA airplanes. The proposed action would require inspecting for cracks and missing rivets in the cabin structure (longeron) adjacent to and aft of the second right hand cabin window, and repairing any cracked structure and installing rivets, if missing. The Federal Aviation Administration (FAA) has received reports of airplanes with cracks in the cabin structure. The airplanes are missing rivets that should have been installed in the cabin structure to secure the frame, splice, and longeron together. The missing rivets, which could lead to cabin structure cracks, prompted the proposed AD action. The actions specified by the proposed AD are intended to prevent structural damage to the cabin caused by missing rivets, which if not corrected, could cause decompression injuries to passengers, structural damage to the fuselage, and loss of the airplane.
